Vertical temperature distribution characteristics of stratified air conditioning with low sidewall air supply and middle sidewall air return in large space building based on brine scale model

Takes the air distribution of a large-scale real-sized building as the prototype, and builds a brine scale model test bench based on the similarity theory. Through the improvement of experimental system, the brine experimental platform has the heat transfer simulation function of the roof and wall. By measuring the brine concentration in vertical direction, obtains the vertical temperature distribution of the prototype with conversion. The experimental results show that the vertical temperature distribution obtained by the brine model experiment is basically consistent with the prototype test results. Takes a large number of experiments in different conditions, and obtains the vertical temperature distribution characteristics of the stratified air conditioning with low sidewall air supply and middle sidewall air return at different stratification height, air supply rates, air supply temperature and return air outlets.
